Abstract (en)
An improved esterification process for producing volatile product esters by reacting a lower linear hydrocarbyl carboxylic acid with an alcohol containing from 2 to 10 carbon atoms, in a substantially non-aqueous medium, the improvement comprising minimizing the amount of acidic sulfate contained in the product ester by employing as the esterification catalyst a long chain alkylbenzene sulfonic acid catalyst, the alkyl radical containing from 8 to 20 carbon atoms, or mixtures of such catalysts.
